VÖGELE Mobile Power Feeder Increasing Footprints In India
State of the art technology from VÖGELE, absolute power for large jobsites
India has the second-largest road network in the world, spanning a total of 6.39 million km as per Economic Survey 2021. This road network transports 64.5% of all goods in the country and 90% of India’s total passenger traffic uses road network to commute.
The National Infrastructure Pipeline of which Bharatmala Pariyojna is a part, have also accelerated the construction of several Greenfield projects including the expressways & mega highways. With such humongous ongoing and targeted construction of road infra in the country, it becomes more pertinent for the use of state of the art -innovative technologies for cost optimisation and quality results.
VÖGELE Mobile Power Feeder offers cutting-edge technology that sets standards in modern road construction both in terms of quality and economic efficiency. This mobile feeder not only continues to gain popularity for use in large highway projects but has also exponentially contributed to deliver excellent paving results. Since 2006, the VÖGELE Mobile Power Feeders, are in use in various National Highway Projects in state of Haryana, Rajasthan, Uttar Pradesh & Gujarat.
Job Site: Delhi – Mumbai Expressway
1350 km Delhi – Mumbai Expressway (DME) project (NH-148N/NE-4) is an under construction 8 lane access-controlled road with a route connecting DND in Delhi with JNPT in Mumbai. It has been designed with a speed limit of 120 km/hr and provision to expand to 12 lanes in the future.
This new greenfield expressway was approved for construction under the Bharatmala Pariyojana programme in 2017. This being a mega Green Field project is one of the ideal project site for use of Mobile Feeder although the following prerequisite was checked/ensured before machine was physically moved to job site.
Total quantity of Asphalt to be paved
Current paving methodology for 8 Lane carriageways of 18.75 m width
Batch (Hot Mix) Plant Capacity
Availability of the paving front or length
Per day paving target (quantity & length)
Average lead of the paving site from plant location
Availability and type of trucks used in Asphalt Mix Transport
Project Name: Package 5 & 6 of Delhi – Mumbai Expressway
Location: Dausa (Rajasthan)
Pavement: Stone Mastic Asphalt (SMA) Width:- 18.75m Layer thickness:- 50mm compacted
Equipments Used
Power feeder - 1 Vogele MT3000-2
Paver - 2 Vogele Super 1800-3 with AB600-3TV Screed
Tandem rollers - Tandem rollers
PTR - 2 Hamm GRW 15
It was more interesting to have this jobsite because the opportunity was to use Mobile Feeder on one units of VÖGELE Asphalt Paver S1800-3 which is working in echelon form with another paver and also to use feeder on both the machine.
The paving process was carried out with AB 600-3 TV screeds paving 18.75 m width of SMA in single pass. MT 3000-2 Power Feeder was used for continuous and jerk free feeding.
Post completion of approx. 9.14 km of paving length and 10,000 ton of material paved construction company site team from Quality check & mechanical reported the following
Continous and more homogeous supply of mix
Uninteruptted paving & avoid feeding of seggreated material to the paver hopper
Jerk free paving operation because of contact less paving
Eliminating the chances of having cold & hot spots in the paving mat, thus eliminating compaction variance
Increase in onboard material capacity
Higher productivity
Reduction in number of paving stops
The outcome was excellent ride quality, surface nish and less manpower requirement during paving, thereby reducing the chances of error due to human intervention in the paving process.
There is no direct contact between tippers/lorries and the pavers which eliminates the jerk transfer from tippers to the pavers diminishes the chances of bump formation on the mat. Non-contact and continuous paving makes the pavement completely undulation free. Homogeneous material being supplied by the conical augers ensures uniform temperature mix being supplied to the paver which eliminates chances of thermal segregation throughout the mat. Two infrared heaters present on the conveyor ensure no materials sticks to the conveyor belt which improves the life of the conveyor.
Power feeders are perfectly suited for hot-to-hot paving in which two pavers works side by side paving large width in single pass with elimination of longitudinal joint.
Paving multiple lanes side-by-side (with adjacent pavers slightly offset) can remove the longitudinal joint between pavers because both mats are hot when initially compacted. Rollers behind the echelon pavers can pass directly over the longitudinal joint while both sides are hot, which results in better compaction.
As per user feedback, “undulation in paved layer by power feeder has been reduced significantly. Surface quality improvement is the utmost advantage of power feeder.”
